Which of the following equations will result in a U-shaped graph? y = 2 x - 4
y = |-4 x|
y = 3 x2 - 5
y = -2 x3

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Asap! will mark brainliest! ( respond asap, it's urgent! : )) what is the slope for equation y =-3x + 8
